Morphology determination of defect-rich diblock copolymer films with time-of-flight grazing-incidence small-angle neutron scattering

The combination of both time-of-flight mode and grazing-incidence small-angle neutron scattering (GISANS) enables the simultaneous performance of several GISANS measurements that differ in wavelength. As a consequence, within one measurement a full set of GISANS patterns related to different scattering vectors, different scattering depths and different resolutions results, which allows the detection of the complex morphology of a defect-rich diblock copolymer film.
